ER degradation-enhancing alpha-mannosidase-like protein 3 (Edem3)

Involved in endoplasmic reticulum-associated degradation (ERAD). Accelerates the glycoprotein ERAD by proteasomes, by catalyzing mannose trimming from Man8GlcNAc2 to Man7GlcNAc2 from the N-glycans.

Seems to have alpha 1,2-mannosidase activity. .
